Launch straight at the drag strip? Or take that road course or autocross track corner just a tick faster? What about an emergency evasive maneuver on the street? All these situations are aided by adding a rear stabilizer bar to your vehicle. The decreased body roll and easing in understeer that a rear sway bar brings to the table makes you wonder why they were not included from the factory. Truth be told, just about every car coming off the assembly line today has a rear stabilizer bar, but back in the day it wasn't deemed necessary with the tire contact patch and tire construction/quality of the time. Today's super grippy plus sized wheel and tire combinations absolutely benefit from adding a rear anti roll bar.

Our splined rear sway bar is a generous .650-inch diameter (5/8-inch) of solid heat treated steel and rides in bronze bushings
